SSTP does not connect to KeenetisOS VPN

Post by valeramalko » Mon Oct 14, 2019 10:24 am

Hello
I have an sstp vpn server on a keenetic router, but the vpn client does not connect to the server, below is the log from the client

Code: Select all

2019-10-14 15:15:54 Wait 5 seconds...
on a router such a log:

Code: Select all

Oct 14 15:15:54 Keenetic_Giga ppp-sstp[11352]: ppp0:: sstp: ppp: read: Input/output error
keeneticOS developers replied that "the client does not know how to handle LCP Configure-Nak"
can this problem be solved?

It's strange because it work with all Windows/Mikrotik implementations.
Maybe the debug log may help to understand the problem.
Anyway the log contains a lot of informations, so is better if you send it to android@colucci-web.it

Here the steps to get the log:
  • edit the VPN
  • tap on "Options"
  • select "Set log level" and set the value to 3
  • save the changes
  • connect the VPN
  • wait for the error
  • disconnect the VPN
  • export and send the log
After the test, remember to edit the VPN and unselect the "Set log option"

Thank you very much for the bug report.
The problem was related to a bug in the LCP negotiation.
The problem has been fixed in the new release 1.00.22 that will be available shortly
